| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

This lesson aligns with the U.S. Common Core State Standards for Mathematics, specifically:
| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction to Ratios | 5 minutes | Introduce the concept of ratios, provide real-life examples (e.g., recipes, scaling). |
| 2 | Checking Previous Homework | 5 minutes | Review homework answers quickly without requesting student presentations; provide feedback. |
| 3 | Interactive Ratio Activity | 10 minutes | Distribute printable ratio cards; guide students to fill them in with examples of ratios. |
| 4 | Guided Practice | 5 minutes | Work through a few example problems as a class, assisting students as needed. |
| 5 | Collection of Cards | 3 minutes | Collect or randomly check the filled cards to assess understanding and provide feedback. |
| 6 | Assignment of Homework | 2 minutes | Assign homework related to ratios without providing specific questions in this plan. |
"Good morning, class! Today we are going to explore an exciting topic in math: ratios. A ratio is a way to compare two quantities. For example, if I have 2 apples and 3 oranges, we can describe that relationship as a ratio of 2 to 3, or written as 2:3. Ratios are everywhere in our daily lives! We see them in recipes, in the ingredients we use, or even when we scale a drawing. Can anyone give me another example of where you might see ratios in real life?"
(Pause for responses and encourage students to share their thoughts.)
"Great examples! Now, let’s dive deeper into understanding ratios together."
"Before we jump into today’s activities, I want to take a moment to check our homework from last night. I hope you all found the practice helpful! I’m going to quickly go over some of the answers. Please take a look at your worksheet and see if you got similar answers."
(Review some key homework problems and provide quick feedback.)
"If you had any trouble, don’t worry! We’ll have plenty of time to practice more today."
"Now let’s get hands-on! I’m going to pass out some printable ratio cards to each of you. On these cards, you will see different situations. Your task is to fill them out with the appropriate ratios based on the scenarios provided. For example, if it says there are 4 cats and 5 dogs, you would write the ratio as 4:5."
(Distribute the ratio cards and give students about 10 minutes to complete this task.)
"Remember to think carefully about each scenario, and if you’re uncertain, raise your hand for help!"
"Fantastic work with the ratio cards! Now, I’d like us to work through a few problems together as a class. Let’s start by looking at this example on the board: 'If there are 8 boys and 6 girls in the class, what is the ratio of boys to girls?'"
(Write the problem on the whiteboard and guide students through the steps on how to find the ratio.)
"Who can tell me how we would write that ratio? Yes, that’s correct! It would be 8:6, but we can also simplify that. How do we simplify it? That’s right, we divide both numbers by 2, which gives us 4:3!"
(Continue with a couple more examples, allowing for student interaction.)
"Time’s up! I hope everyone filled in their ratio cards thoughtfully. Now, I would like you to pass your cards to the front. I’ll quickly glance through some of them to see how well we understand this topic."
(Collect the cards. While collecting, walk around to check a few students’ work. Provide immediate feedback as necessary.)
"This will help me know how we’re doing as a class. Remember to keep practicing with ratios!"
"Before we end today’s lesson, I want to let you know about your homework. You'll have some exercises related to ratios to work on at home. Make sure to review today’s lesson while you complete the homework—it will definitely help you!"
(Inform the students that the homework will be posted on the board for them to copy down.)
"Thank you for your great participation today! Remember to think of ratios in your everyday life. See you next class!"
Define the term 'ratio'. What does it mean and where do we see it in daily life?
Given the following quantities, express each as a ratio:
Simplify the following ratios:
A recipe calls for 2 cups of flour and 3 cups of sugar. What is the ratio of flour to sugar?
If there are 15 students in a classroom and 10 of them are boys, what is the ratio of boys to students?
In a survey of fruit preferences, 8 people like apples, 10 like bananas, and 6 like oranges. Write the ratios of each fruit preference in relation to the total number of people surveyed.
If the ratio of cats to dogs in a pet store is 3:5, and there are 15 cats, how many dogs are there? Show your work.
Create your own real-world example of a ratio. Describe the scenario and then express the ratio in both fractional and colon form.
Discuss why it is important to understand ratios. Provide at least two reasons based on your class discussions and activities.
